Good day.
First, I know they are many posts that relate to my issue, but none provided me with a fix. 
Running:
Mongo Server Community 5.0.5
Windows Server 2019
The service runs with a domain user for which we gave full control over the root path of D:\Mongo\ (in which is the data and log folder). Additionally, we’ve also setup our AV to exclude scanning within D:\Mongo\ too !
Every so often (too often!) the mongod.exe process still seems to crash with a FileRenamedFailed: Access is denied… error. Here’s a snipped of the log file:

In all the posts out there, none of them resolved this crash for us:
-
Most of them related to an AV scanning files with the /data/: we’ve excluded scanning within the folder!
-
Some talk about permissions problems: we’ve given full control to the user running mongod within the root of the Mongo files!
-
I’ve even seen posts talking about a bad server locale setup (but that would be when the log shows unicode chars not processed properly or something (log would show something like
{"message":"DBException::toString(): FileRenameFailed: \ufffdv\ufffd\ufffd...), but that doesn’t seem to be our case from viewing our log. Plus, our server is set with a “English” local:
I’m running out of ideas here… Upgrade to latest Mongo? But why haven’t I found anything regarding this that says you need to upgrade if that’s the case?
Any ideas would be super appreciated. Much thanks for your time folks.

Although, I’m still puzzled as to why we’re getting the crash. I mean, if doing an upgrade fixes it, then I should be able to find the relevant fix that resolves the issue, but didn’t find anything yet…
